Question

Determine if the following reactions will form a precipitate when solutions of the reactants are mixed. If a
precipitate is formed when the reactants are mixed, write the balanced formula unit, the complete ionic and
the net ionic equations for the reactions. If a precipitate does not form when the reactants are mixed, write NR (no reaction) to the right of the arrow. Do not forget to include the physical states of the reactants and products; (aq), (s), (l), (g) in your three solution equations.

a. Fe(NO3)2 (aq) + K3PO4 (aq)
b. Ba(OH)2 (aq) + Pb(ClO3)2 (aq)
c. Al(ClO4)3 (aq) + Na2SO3 (aq)
d. CaCl2 (aq) + (NH4)2SO4 (aq)
e. LiCH3COO (aq) + MgCl2 (aq)

Explanation / Answer

a. Fe(NO3)2 + K3PO4 = Fe3(PO4)2 + KNO3

b.Ba(OH)2(aq) + Pb(ClO3)2(aq) = Pb(OH)2(aq) + Ba(ClO3)2(aq)

c. equation Al(ClO4)3+Na2SO3=Al2(SO4)3+NaClO4 is an impossible reaction

d.  equation (NH4)2SO4+CaCl2=(NH4)Cl2+CaSO4 is an impossible reaction

correct form is => (NH4)2SO4 + CaCl2 = (NH4)2Cl2 + CaSO4

e.  equation MgCl2(aq)+AgNO3(aq)=Mg(NO3)2+AgCl2(aq) is an impossible reaction

correct form is =>MgCl2(aq) + AgNO3(aq) = AgCl(s) + Mg(NO3)2(aq)
